Question: If a black sheep gives 22 ounces of wool to his master, 23 ounces to his dame, and 19 ounces to the little boy who lives down the lanLower Elementary:e, then how many ounces of wool does the black sheep give away in total?
Answer: 64 ounces
Solution: To find the total number of ounces of wool, we add 22 + 23 = 45 ounces, + 19 = 64 ounces.
Upper Elementary:
Question: A little pig builds a brick house that is 10â…” feet wide and 12â…” feet long. What is the perimeter of the little pig’s house?
Answer: 46â…” feet
Solution: First, we can add together the two shorter sides: 10â…” + 10â…” = 21â…“ feet. Next, we add the two longer sides: 12â…” + 12â…” = 25â…“. Now, if we add the short sides and the long sides together, we’ll have the whole perimeter: 21â…“ + 25â…“ = 46â…” feet.
Middle School:
Question: Jack casts an 8’ shadow. If Jack is 5’ tall, then how tall is a beanstalk that casts a 1,600’ shadow?
Answer: 1,000 feet
Solution: Jack is five-eighths of his shadow’s length. So, the bean stalk’s height will be five-eighths of its shadow’s length. One eighth of 1,600 feet is 200 feet, so five-eighths of 1,600 feet is 200 × 5 = 1,000 feet.
Algebra and Up:
Question: A tortoise and a hare begin a 4–mile race at the same time. The tortoise travels 2 miles per hour, and the hare travels 24 miles per hour. After the hare races for 8 minutes, he stops to take a nap. The tortoise passes the hare and wins the race. How much time does it take for the tortoise to reach the finish line after it passes the hare?
Answer: 24 minutes
Solution: First, we need to know how far the hare gets in 8 minutes (or 2/15 of an hour): 24 mph × 2/15 hr = 16/5 miles. That means that there are 4/5 of a mile left to go for the tortoise after it passes the hare. To find the amount of time, we solve for t: 4/5 of a mile = 2 mph × t, so t = 2/5 of an hour, or 24 minutes.
